Walsh is now a conservative talk radio host[5] on several radio stations in major U.S. cities.[6] The radio show has been syndicated nationwide by the Salem Radio Network since February 2017.[7]

Walsh declared that if Hillary Clinton were elected president in the 2016 U.S. presidential election, he would run for president himself in 2020.[8] Since Donald Trump defeated her, Walsh chose not to run. However, Walsh began to vocally favor the Robert Mueller investigation and increasingly criticized President Trump, eventually rescinding his endorsement of the president and calling him a "traitor."[9]
